Getting access to a JavaScript class from TypeScript and initializing it

I have integrated jsPDF by adding its jspdf.min.js file to my project.

However, I am facing an issue when trying to use it within a TypeScript class. The error message states that jsPDF is unknown:

  btnPrintReportClick() {
        var pdf = new jsPDF();
        pdf.fromHTML($('.container').html(), 15, 15, { 'width': 170 });
        pdf.save('file_name.pdf');
    }

To integrate jspdf into your project, make sure to include the definition file.

If you're currently loading jspdf by inserting a script tag in your HTML page, you can easily add a triple-slash-directive to your typescript file like this:

/// <reference path="PATH/TO/jspdf.d.ts />
